Hi, I have a problem with my dancer webapp deployment. I don't know where to look anymore. I had the old version of my webapp deployed the same way and it worked well. Now, I update it and it doesn't work any more. Dancer is and was version 1.2003. I updated Plack to current version, but no change. I had it in Apache using plack like described in Deployment.pod. Current setup: <VirtualHost 85.xxx.36.140:80> Servername spk.mimo-project.eu DocumentRoot /var/www/vhosts/mimo-project.eu/webapps/Salsa_OAI #SetEnv DANCER_ENVIRONMENT "production" ErrorLog /var/www/vhosts/mimo-project.eu/webapps/logs/error_log CustomLog /var/www/vhosts/mimo-project.eu/webapps/logs/access_log common <Directory /var/www/vhosts/mimo-project.eu/webapps/Salsa_OAI/public> AllowOverride None Order allow,deny Allow from all </Directory> <Location /> SetHandler perl-script PerlHandler Plack::Handler::Apache2 PerlSetVar psgi_app /var/www/vhosts/mimo-project.eu/webapps/Salsa_OAI/bin/app.pl </Location> </VirtualHost> After update, I get a segmentation fault in /var/logs/apache2/error.log (ubuntu) everytime I try to access webapp: [Thu Jan 20 18:20:18 2011] [notice] child pid 32575 exit signal Segmentation fault (11) That's all I get (unless I switch to development environment, as above). The strange thing is that I can run the webapp as standalone, both in production and development environment. I can run it also thru plackup via HTTP::Server::Simple. Somethine else. I changed the httpd.conf file and tried both production and development mode. Debug messages then go to /var/logs/apache2/error.log although I explicitly specify ErrorLog /var/www/vhosts/mimo-project.eu/webapps/logs/error_log I checked my paths a hundred times. The ErrorLog file exists. I also tried to make sure that the permissions work and tried with 777 just to be sure. But why doesn't apache log the errors in the ErrorLog which I gave it? In development mode, I see that my dancer app fails during initialization when it loads the sqlite db. Why would it do so only when started from apache? I hope you have an idea. Thanks Maurice
